3. Process description:

KDON-350/500 air separation plant is of low pressure process.

Raw air comes from air, goes through air filter for removal of dust
andother mechanical particle and enters non-lub air compressor to
be compressed by two stage compressor to approx. 0.65MPa(g).It goes
through cooler and enters precooling unit to be cooled to 5～10℃.
Then it goes to switch-over MS purifier for removal of moisture,
CO2, carbon hydrogen. Purifier consists of two molecular sieve
filled vessels. One is in use while anther is under regeneration by
waste nitrogen from the cold box and through heater heating.

After purified, small part of it is used as bearing gas for turbine
expander, other enters cold box to be cooled by reflux(pure oxygen,
pure nitrogen and waste nitrogen) in main heat exchanger. Part of
air is abstracted from the middle part of main heat exchanger and
goes to expansion turbine for production of cold. Most of expanded
air goes through subcooler which is cooled by oxygen from upper
column to be delivered to upper column. Small part of it goes
through bypass to waste nitrogen pipe directly and is reheated to
go out of the cold box. The other part of air continues to be
cooled to near liquid air tempt to lower column.

In lower column air,air is separated and liquified as liquid
nitrogen and liquid air. Part of liquid nitrogen s abstracted from
the top of the lower column. Liquid air after subcooled and
throttled is delivered to the middle part of upper column as
reflux.

Product oxygen is abstracted from the lower part of upper column
and reheated by expanded air subcooler, main heat exchange. Then it
is delivered out of column. Waste nitrogen is abstracted from the
upper part of upper column and is reheated in subcooler and main
heat exchanger to go out of column. Part of it is used as
regeneration gas for MS purifier. Pure nitrogen is abstracted from
the top of the upper column and is reheated in liquid air , liquid
nitrogen subcooler and main heat exchanger to be delivered out of
the column.

Oxygen out of the distillation column is compressed to customer.
